  2. Monthly Palmer Drought Severity Index (PDSI)

Monthly Palmer Drought Severity Index (PDSI) calculated from observed surface air temperature and precipitation from 1870-2005. Calibration (or reference) period is 1950-1979. Documention: Dai, A., K. E. Trenberth, and T. Qian, 2004: A global data set of Palmer Drought Severity Index for 1870-2002: Relationship with soil moisture and effects of surface warming. J. Hydrometeorology, 5, 1117-1130. Data source: Dr. A. Dai/NCAR (adai@ucar.edu). See http://www.cgd.ucar.edu/cas/catalog/climind/pdsi.html for updates.
